mcp-integration

The mcp-integration skill facilitates the integration of Model Context Protocol (MCP) servers into Claude Code plugins, solving the challenge of connecting plugins to external services and APIs. By leveraging MCP, developers can expose external service capabilities as tools within Claude Code, enabling structured communication with databases, APIs, file systems, and other external resources. This skill is particularly useful for plugin developers who need to extend their plugins' functionality by interfacing with external services seamlessly and securely.

The skill provides multiple configuration methods, including a dedicated `.mcp.json` file or inline configuration within `plugin.json`, allowing flexible setup based on plugin complexity. It supports various server types such as local stdio processes, SSE for server-sent events, HTTP REST APIs, and WebSocket for real-time communication. Each server type has specific use cases, from local file access to OAuth-based cloud services and low-latency real-time streaming. The skill also handles environment variable expansion, OAuth flows, process management, and token handling, simplifying authentication and integration tasks for developers.

Typical use cases include integrating cloud services like Asana or GitHub, connecting local databases, creating custom MCP servers for internal tools, or enabling real-time data streaming. The target users are plugin developers and technical teams who aim to extend the capabilities of Claude Code plugins through robust, standardized connections to external tools and services. By using this skill, developers can maintain clear separation of configuration, manage multiple MCP servers efficiently, and ensure secure and reliable interactions with external resources.
